Supplying Surplus Electricity for Local Use from Solar Irrigation in Bangladesh

In the rural regions of Bangladesh, diesel fuel persists as a predominant resource for irrigation purposes, notwithstanding its exorbitant costs, logistical difficulties, and detrimental environmental consequences. In light of these challenges, the government of Bangladesh is actively pursuing alternative solutions. The utilization of renewable energy is on the rise, in accordance with the United Nations' Sustainable Development Goal 7. Solar irrigation systems present a sustainable and environmentally viable alternative. The Infrastructure Development Company Limited (IDCOL) has commenced solar irrigation pump initiatives in various locations, aiming to establish 10,000 systems by the year 2027. As of March 2024, IDCOL had sanctioned 1,515 solar pumps, resulting in a cumulative generation capacity of approximately 40 MWp. These initiatives possess the potential for enhanced productivity by harnessing surplus electricity during the off-peak season, during which the systems remain inactive for over half of the year. If this excess energy can be effectively integrated into the national grid or distributed locally, the previously untapped potential can be fully actualized. This study investigates effective strategies for the utilization of surplus electricity generated by solar irrigation systems to the benefit of local communities.
